Hi All,

I have just bought a 2001 TT 225. It drove like a dream on the test drive so I bought it. However on the way the check engine light came on but still drove great.
I took at to a friends house and got the fault code read. It came back with P0171 (system too lean bank 1). He cleared the fault and I took it for a drive back home and the car hesitated/misfired when accelerating breifly then it was fine for the next 10 miles with no CEL.

Any ideas? MAF? o2 sensor?

Thanks,
Barry.

Yeah I had a similar experience with an Impreza. Bought it for 5grand in 2004 and and with 3 months I had spent the same again keeping it on the road and then it went steadily up from there. Ended up hating it and giving the thing away.

hi there
had this problem twice on my wifes tt. 1st time it was breather hoses split. 2nd time it was a vacume pipe off at the plenum. bothe times it came up with bank 1 fuel to lean. have a check of your breather system of hoses and your vacume pipes. easy fix if it is but i would get new ones asap. otherwise could cause more probs in the future.

Update: checked for leaks, nothing obvious. Tried swappin maf from a 180 but thats a smaller diameter. So have unplugged the maf and the car has boost again but now the traction light has come on.
So I think it needs a new maf and then erase the codes and see how it goes.
Any other advice?

Hi, As I suggested replace the MAF with genuine Bosch, fault light should clear after a couple of runs.
Hoggy. :D

Many thanks hoggy. Next question where is cheapest for a maf. I checked euro carparts last night and they listed them for £68 but now I can't find them on there site.
